Description

Technical Field

[0001] This utility model relates to the field of pipe fittings, and in particular to a liquid inlet assembly for a medical device cleaning device. Background Technology

[0002] The medical device cleaning equipment used by medical institutions is a regular cleaning basket. For medical devices with lumens, the regular cleaning basket does not have an irrigation cleaning interface and cannot perform irrigation cleaning.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN209077253U discloses a medical device cleaning basket, including a split-type cleaning basket. The split-type cleaning basket includes: a basket body, comprising a base and side walls, the base and side walls forming a cleaning space for accommodating medical devices; a basket cover, movably connected to one side wall of the basket body; and a diversion box, fixed to the side wall, including a box body, the box body having an outwardly communicating inlet and an inwardly communicating connector for connecting to the lumen irrigation interface of the medical device. During operation, the cleaning solution flows through the inlet and multiple connectors into the lumen of the medical device for lumen irrigation and cleaning.

[0004] When using the above technical solution, since multiple connectors are connected to the same inlet, not all connectors can connect to the lumen of the medical device and participate in the cleaning process. This is determined by the number of lumens in the medical device itself. As a result, cleaning solution will also flow out from connectors that are not involved in the cleaning process. On the one hand, this wastes the cleaning solution, and on the other hand, it reduces the cleaning pressure and cannot guarantee the perfusion cleaning effect on the lumen. Utility Model Content

[0005] To address the technical problems of wasted cleaning fluid and reduced rinsing effect in the pipe connector assembly of medical device cleaning devices in the prior art, this utility model provides a liquid inlet assembly for medical device cleaning devices, which can reduce cleaning fluid waste, ensure a certain cleaning pressure, and improve the cleaning effect.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a liquid inlet component for a medical device cleaning device, including a housing, a liquid inlet pipe provided on the housing, and multiple pipe joints, the pipe joints being provided on the housing and communicating with the interior of the housing, a valve flap being provided on the inner wall of the pipe joint, the valve flap being made of a soft elastic material, the valve flaps being inclined, the valve flaps being able to swing and deform under the action of external force, and the sealing end of the valve flap facing the liquid inlet end of the pipe joint.

[0007] This invention incorporates valve discs within multiple pipe joints, allowing the valve discs not connected to the pipe to automatically swing and deform under the pressure of the cleaning fluid. This alters the throttling area within the pipe joint and can even completely cut off the flow, reducing unnecessary waste of the cleaning fluid, minimizing pressure loss, and ensuring effective cleaning of the pipeline.

[0008] Furthermore, there are two valve discs, which are symmetrically arranged about the center face of the pipe joint. The sealing ends of the two valve discs can approach each other until they abut under the action of external force. When the valve discs abut, the two valve discs form a wedge-shaped structure.

[0009] This invention features two valve discs that can swing and deform under relatively low pressure from the cleaning fluid, changing the throttling area and making the response more sensitive. At the same time, the two valve discs can close together to cut off the flow at the pipe joint, further reducing leakage at pipe joints that are not connected to the pipe.

[0010] Furthermore, the sealing end of the valve disc is provided with a sealing surface, and after the two valve discs abut and close, the sealing surface is perpendicular to the center plane of the pipe joint.

[0011] This invention improves the stability and sealing of the two valve discs when they are closed by setting a sealing surface, thereby further reducing cleaning fluid leakage.

[0012] Furthermore, the valve disc is located at the liquid outlet end of the pipe joint.

[0013] This invention, by placing the valve disc at the liquid outlet end, allows the pipeline to fully support the valve disc, preventing the unsupported part of the valve disc from deforming and blocking the pipe opening under the action of the cleaning fluid, thus affecting the entry of the cleaning fluid into the pipeline for cleaning.

[0014] Furthermore, the pipe fitting is made of a soft, elastic material, and each end of the pipe fitting is provided with an inlet hole and an outlet hole.

[0015] This invention uses a pipe fitting made of soft, elastic material, which can produce elastic deformation and is suitable for pipes of various diameters, making it more widely applicable.

[0016] Furthermore, the housing is provided with a plurality of liquid outlet pipes, the number of which is the same as the number of pipe joints. The pipe joints are sleeved on the liquid outlet pipes. The liquid inlet is a drum-shaped structure with the middle part of the liquid inlet protruding inward.

[0017] This invention increases the deformation of the liquid inlet by setting a drum-shaped structure in the liquid inlet, thereby increasing the connection strength between the pipe joint and the liquid outlet pipe of the shell and preventing the pipe joint from falling off.

[0018] Furthermore, the diameter of the smallest part of the liquid inlet is D1, and the diameter of the liquid outlet is D2, where D1 > D2.

[0019] This invention improves the cleaning effect by making the outlet hole smaller, thereby increasing the outlet flow rate and the pressure of the cleaning fluid entering the pipeline.

[0020] Furthermore, both the valve disc and the pipe joint are made of silicone.

[0021] As can be seen from the above technical solutions, this utility model has the following advantages:

[0022] This invention provides a liquid inlet assembly for a medical device cleaning device. By incorporating valves within multiple pipe joints, the valves of the non-connected pipe joints can automatically swing and deform under the pressure of the cleaning fluid, altering the throttling area within the joint and even completely cutting off the flow. This reduces unnecessary waste and pressure loss of the cleaning fluid, ensuring effective cleaning of the pipes. The use of two valves allows for swinging and deformation even under relatively low cleaning fluid pressure, changing the throttling area and improving responsiveness. Furthermore, the abutting closure of the two valves cuts off the flow at the pipe joint, further reducing leakage at non-connected pipe joints. The inclusion of a sealing surface enhances the sealing effect when the two valves are closed. The stability and sealing performance further reduce cleaning fluid leakage; by placing the valve disc at the outlet end, the pipeline can fully support the valve disc, preventing the unsupported part of the valve disc from deforming and blocking the pipe opening under the action of the cleaning fluid, thus affecting the entry of the cleaning fluid into the pipeline for cleaning; by using a soft and elastic pipe fitting, it can produce elastic deformation, adapting to pipes of various diameters, thus expanding its application range; by setting the inlet hole into a waist-drum-shaped structure, it can increase the deformation of the pipe fitting on the outlet pipe, increasing the connection strength between the pipe fitting and the outlet pipe of the housing, and preventing the pipe fitting from falling off; by setting the outlet hole to be narrower, it can increase the outlet flow rate, increase the pressure of the cleaning fluid entering the pipeline, and thus improve the cleaning effect.

[0033] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0035] like Figure 1 and Figure 2As shown in the figure, this specific embodiment provides a liquid inlet assembly for a medical device cleaning device, including a housing 2 and multiple pipe connectors 3; the housing 2 is provided with multiple liquid outlet pipes 4, the number of which is the same as the number of pipe connectors 3, and the pipe connectors 3 are sleeved on the liquid outlet pipes 4. A liquid inlet pipe 1 is also provided at one end of the housing 2 opposite to the liquid outlet pipes 4. The pipe connectors 3 are disposed on the housing 2 and communicate with the interior of the housing 2. A valve disc 5 is provided on the inner wall of the pipe connector 3. The valve discs 5 are made of soft elastic material and are all inclined. The valve discs 5 can swing and deform under external force. The valve discs 5 are densely packed. The sealing end faces the liquid inlet end of the pipe joint 3, that is, the tilt direction of the valve disc 5 is opposite to the flow direction of the cleaning fluid; in this specific embodiment, a valve disc 5 is provided; when no corresponding pipe 9 is inserted into the pipe joint 3, when the valve disc 5 swings forward and downward (with the direction of the cleaning fluid flow as forward) and elastically deforms under the impact of the cleaning fluid, the sealing end of the valve disc 5 can adhere to the inner wall of the pipe joint 3, thereby changing the throttling area in the pipe joint 3 and reducing the leakage of the cleaning fluid. When the pipe joint 3 is connected to the pipe 9, the valve disc 5 swings backward and upward under the action of the pipe 9 until it is located between the pipe 9 and the inner wall of the pipe joint 3, without obstructing the flow of the cleaning fluid.

[0036] This specific embodiment provides valve discs 5 in multiple pipe joints 3, allowing the valve discs 5 not connected to the pipe 9 to automatically swing and deform under the pressure of the cleaning fluid, changing the throttling area within the pipe joint 3, avoiding a large amount of leakage in the pipe joint 3 that is not involved in cleaning, reducing unnecessary waste of cleaning fluid, reducing pressure loss of cleaning fluid, and ensuring the cleaning effect on the pipe 9.

[0037] like Figure 3 As shown, in this specific embodiment, the valve disc 5 has an elliptical structure, and the end face area of ​​the valve disc 5 is larger than the cross-sectional area obtained by a cylindrical structure with the same diameter as the inner diameter of the pipe joint 3 at the same tilt angle. With this setting, the contact area between the edge of the valve disc 5 and the inner wall of the pipe joint 3 can be increased, and it has a larger friction force, which prevents the valve disc 5 from swinging forward under the impact of the cleaning fluid, thus affecting the throttling effect of the valve disc 5.

[0038] like Figure 2 As shown, in this specific embodiment, the valve disc 5 is disposed at the liquid outlet end of the pipe joint 3; by disposing of the valve disc 5 at the liquid outlet end, the pipe 9 can completely support the valve disc 5, preventing the unsupported part of the valve disc 5 from deforming and blocking the pipe opening under the action of the cleaning fluid, thus affecting the entry of the cleaning fluid into the pipe 9 for cleaning.

[0039] To ensure that the pipe fitting 3 is suitable for insertion into various pipes 9, in this specific embodiment, the pipe fitting 3 is made of a soft, elastic material. This design allows the pipe fitting 3 to deform under the influence of pipes 9 of different diameters and the outlet pipe 4, thereby adapting to various sizes of pipes 9 and the housing 2, and providing a good sealing effect; furthermore, as... Figure 2 As shown, the pipe connector 3 is provided with an inlet hole 7 and an outlet hole 6 at both ends. The inlet hole 7 has a drum-shaped structure, and the middle part of the inlet hole 7 protrudes inward. With this design, after the pipe connector 3 is installed on the outlet pipe 4, the inlet hole 7 can generate a large elastic deformation, which increases the connection strength between the pipe connector 3 and the outlet pipe 4 of the housing 2 and prevents the pipe connector 3 from falling off. Furthermore, the diameter of the narrowest part of the inlet hole 7 is D1, and the diameter of the outlet hole 6 is D2, where D1 > D2. By making the outlet hole 6 narrower, the outlet flow rate can be increased, the pressure of the cleaning liquid entering the pipe 9 can be increased, and thus the cleaning effect can be improved.

[0040] Soft elastic materials refer to materials with high elastic deformation capacity (can return to their original shape after being compressed or stretched) and flexibility (can be bent, folded or fit irregular surfaces), such as silicone, thermoplastic elastomers, natural rubber and other materials. In this specific embodiment, both the valve disc 5 and the pipe joint 3 are made of silicone material and are injection molded as one piece.

[0041] In this specific embodiment, the shell 2 is made of stainless steel and is equipped with five liquid outlet pipes 4 and pipe joints 3.

[0042] The process of using the liquid inlet assembly of this medical device cleaning device is as follows:

[0043] Insert the tubing 9 of the medical device to be cleaned into the corresponding connector 3. The cleaning fluid enters the housing 2 through the inlet pipe 1 and then into each outlet pipe 4. In the connector 3 where the tubing 9 is inserted, the valve 5 is pushed between the inner wall of the tubing 9 and the connector 3, allowing the cleaning fluid to flow smoothly from the connector 3 into the tubing 9 for cleaning. In the connector 3 where the tubing 9 is not inserted, the valve 5 swings forward and downward under the impact of the cleaning fluid. Due to the large area of ​​the valve 5, it cannot fully follow the flow direction of the cleaning fluid during the swing. Its sealing end adheres to the inner wall of the connector 3 under pressure, preventing the connector 3 from conducting and the cleaning fluid from flowing out of the outlet hole 6. Specific Implementation Method Two

[0045] like Figure 5 , Figure 7 and Figure 8As shown, this specific embodiment is basically the same as the structure of specific embodiment one, the difference being that: there are two valve discs 5, the two valve discs 5 are symmetrically arranged about the center face of the pipe joint 3, the sealing ends of the two valve discs 5 can approach each other until they abut under the action of external force, and when the valve discs 5 abut, the two valve discs 5 form a wedge-shaped structure.

[0046] This specific embodiment, by setting two valve discs 5, can achieve abutment closure after the valve discs 5 swing at a small angle, thus cutting off the flow in the pipe joint 3. Compared with using a single valve disc 5, the response is more sensitive. At the same time, the two valve discs 5 can disperse the fluid impact force to both sides, reduce the stress on a single valve disc 5, improve closure stability, further reduce leakage, and each valve disc 5 bears a smaller strain, reducing the material fatigue rate and extending service life.

[0047] like Figures 5 to 7 As shown, preferably, the sealing end of the valve disc 5 is provided with a sealing surface 8. After the two valve discs 5 are closed by abutting, the sealing surface 8 is perpendicular to the center plane of the pipe joint 3. With this arrangement, when the valve disc 5 is closed, the sealing surface 8 at the sealing end is perpendicular to the flow direction of the cleaning fluid. The static pressure of the cleaning fluid acts directly on the normal direction of the sealing surface 8, pushing the valve disc 5 to fit more tightly against the pipe wall, forming a surface contact seal. The sealing surface 8 is not easily pushed open by the lateral flow force under the impact of the cleaning fluid, and has high stability, especially under high flow rate or pulse flow conditions.

[0048] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0049] 1. By setting valve discs 5 in multiple pipe joints 3, the valve discs 5 of the pipe joints 3 that are not connected to the pipe 9 can automatically swing and deform under the pressure of the cleaning fluid, changing the throttling area in the pipe joint 3 or even completely cutting off the flow in the pipe joint 3, reducing unnecessary waste of cleaning fluid, reducing pressure loss of cleaning fluid, and ensuring the cleaning effect on the pipe 9.

[0050] 2. By setting two valve discs 5, they can swing and deform under the action of a small pressure of the cleaning fluid, change the throttling area, and react more sensitively. At the same time, the two valve discs 5 can close together to cut off the flow of the pipe joint 3, further reducing the leakage of the pipe joint 3 without the pipe 9.

[0051] 3. By setting the sealing surface 8, the stability and sealing performance of the two valve discs 5 when closed can be improved, further reducing cleaning fluid leakage;

[0052] 4. By setting the valve disc 5 at the liquid outlet end, the pipeline 9 can fully support the valve disc 5, preventing the unsupported part of the valve disc 5 from deforming and blocking the pipe opening under the action of the cleaning fluid, thus affecting the entry of the cleaning fluid into the pipeline 9 for cleaning.

[0053] 5. By using a soft and elastic material for the pipe fitting 3, it can produce elastic deformation, adapting to pipes 9 of various diameters for insertion, thus having a wider range of applications.

[0054] 6. By setting the liquid inlet hole 7 into a waist drum-shaped structure, the deformation of the pipe joint 3 on the liquid outlet pipe 4 can be increased, the connection strength between the pipe joint 3 and the liquid outlet pipe 4 of the shell 2 can be increased, and the pipe joint 3 can be prevented from falling off.

[0055] 7. By making the outlet hole 6 smaller, the outlet flow rate can be increased, the pressure of the cleaning liquid entering the pipe 9 can be increased, and thus the cleaning effect can be improved.

[0056] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
